The open gridwork may be part of a shoe midsole or may constitute a shoe midsole.

An overlay layer (150) of high refractive index material is then deposited on the corrugated grating.

The open gridwork is flat, corrugated, or double corrugated.

This nanomask includes a substantially periodic array of substantially parallel elongated elements having a wavelike cross-section.

The corrugated pipe sealing assembly comprises an inner corrugated pipe (3), an outer corrugated pipe (4), an upper corrugated header (5), a first lower corrugated header (2) and a second lower corrugated header (1).

An overlay layer (150) of high refractive index material is then deposited on the corrugated grating.

The first single-faced web is conveyed along a track into a double backer forming a first corrugated material.

The corrugated tube (13) arrays indented grooves and protruding bands (15) in alternation in the lengthwise direction.

Alternatively, the first corrugated panel, the ballistic cloth, and the second corrugated panel can be coupled together using a fastener that compresses the ballistic cloth between the first corrugated panel and the second corrugated panel.

The outer corrugated pipe (4) is sleeved outside the inner corrugated pipe (3).

One end of the inner corrugated pipe (3) is fixed with the upper corrugated header (5), while the other end is fixed with the second lower corrugated header (1).

Corrugated board is then further processed into corrugated boxes used for packaging.

One end of the outer corrugated pipe (3) is fixed with the upper corrugated header (5), while the other end is fixed with the first lower corrugated header (2).
